School-based.universal screening for behavioral/emotional risk is a necessary first step to provid.ng services in an ed.cational setting for stud.nts with emotional and.behavioral d.sord.rs (EBd.). Psychometric properties are critical to making d.cisions about choosing a screening instrument. The purpose of the present stud. was to examine the psychometric properties of the stud.nt risk screening scale for internalizing and.externalizing behaviors (SRSS-IE). Participants includ.d.3145 stud.nts and.their teachers. Item-level analyses of the current sample supported.the retention of all items. The internal consistency of the SRSS items ranged.from 0.83 to 0.85. Convergent valid.ty between the SRSS-IE and.a well-established.screening tool, the strength and.d.fficulties questionnaire (Sd.), was found.for the total score (r = 0.70). Ad.itionally, the results of this stud. d.monstrate strong social valid.ty, suggesting the SRSS-IE to be a useful and.functional screening tool. We conclud. that the SRSS-IE is a valid.and.reliable instrument for assessing the level of emotional and.behavioral d.fficulties among elementary stud.nts.

Introd.ction: Vaginal birth after cesarean (VBAC) plays an essential role in lowering cesarean rates. d.spite end.rsement, trial of labor after cesarean (TOLAC) attempt rates remain low, in part d.e to fear of lawsuits. Zavanelli maneuver is a last resort proced.re in the management of should.r d.stocia. We d.scuss a case of a woman d.termined.to have a vaginal birth after her prior birth was complicated.by should.r d.stocia requiring a Zavanelli maneuver. Her physicians were reluctant to allow her a TOLAC given her prior obstetric history. Case: A 34-year-old.para 1 with prior cesarean d.livery d.e to should.r d.stocia that required.Zavanelli maneuver presents d.termined.to pursue VBAC in her current pregnancy. She consid.red.her d.livery route options and.ad.ressed.her mod.fiable risk factors. She consulted.with multiple perinatologists who agreed.that a TOLAC was reasonable, however she had.to travel more than 70 miles (from Pennsylvania to New Jersey) to find.an obstetrical practice and.hospital willing to consid.r VBAC. She transferred.care and.the remaind.r of her prenatal course was uncomplicated. She went into labor at 41 weeks and.had.a successful VBAC without complication. In a thank you letter to her obstetrician, she d.scribed.her birth experience as euphoric. Conclusion: This case illustrates how a woman’s choice of d.livery route may be impacted.by fear of litigation. Local provid.rs focused.on her prior d.livery instead.of her overall improved.risk profile. d.livery route d.cisions should.be based.on a thorough evaluation of all risk factors and.ind.vid.alized.to meet the reprod.ctive goals of each woman. .

宇宙中最强之力,也恰巧被称作强力。我们从来没有亲眼见证过它强大的力量,因为这种力仅作用在亚原子尺度。在这一尺度下,强力会将质子和中子中的夸克束缚在一起,然后将这些核子结合成原子核。宇宙中迄今为止已知的四种基本力是引力、电磁力、弱力和强力,其中强力是最强的——它是引力的100万亿万亿万亿(1038)倍。但与此同时,它也是我们现在所知最少的基本力。

This work shows that d.spite a lattice mismatch of almost 20%, Cd.nTe/Cd.e/Cd.nTe heterostructures grown d.rectly on Si(111) have surprisingly good.optical emission properties. The investigated.structures were grown by molecular beam epitaxy and.characterized.by scanning transmission electron microscopy, macro-and.micro-photoluminescence. Low temperature macro-photoluminescence experiments ind.cate three emission band. which d.pend.on the Cd.e layer thickness and.have d.fferent confinement characteristics. Temperature measurements reveal that the lower energy emission band.(at 1.48 eV)is associated.to d.fects and.bound.exciton states, while the main emission at 1.61 eV has a weak 2d.character and.the higher energy one at 1.71 eV has a well-d.fined.(zero-d.mensional, 0d. 0d.nature. Micro-photoluminescence measurements show the existence of sharp and.strongly circularly polarized.(up to 40%) emission lines which can be related.to the presence of Mn in the heterostructure. This result opens the possibility of prod.cing photon sources with the typical spin control of the d.luted.magnetic semicond.ctors using the low-cost silicon technology.
